postgresql (SL7)

The following packages have been upgraded to a later upstream version:
postgresql (9.2.23).

Security Fix(es):

* It was found that authenticating to a PostgreSQL database account with
an empty password was possible despite libpq’s refusal to send an empty
password. A remote attacker could potentially use this flaw to gain access
to database accounts with empty passwords. (CVE-2017-7546)

* An authorization flaw was found in the way PostgreSQL handled access to
the pg_user_mappings view on foreign servers. A remote, authenticated
attacker could potentially use this flaw to retrieve passwords from the
user mappings defined by the foreign server owners without actually having
the privileges to do so. (CVE-2017-7547)
